Sash and sash guides for windows



Oct. 29, 1957 T. l.. MCDONOUGH sAsH AND sAsH GUIDES FOR wINDows Filed Aug. l1. 1954 o n\ 8 4 M QQ 6 V 1/ WW l////% United States This invention relates to Window and sash guides and is particularly concerned with preformed metal sashes for retaining thewindow glass. and preformed cooperating metal guides for slidablyk receiving such sashes.

It is amongthe primary and more general objects of the present invention to. provide a new and improved metal- 'sash and sash guide combination of enhanced simplicity, durabilityand etiiciency `and one well adapted to meet 4thedemands of economic manufacture.

More specifically it is among the objects of the invention to provide a novel and etiicient metallic sash and sash guide construction providing in combination such frietional relationship between parts as to avoid the necessity for springs sash-weight or like counter balance means usually required for retention `of the sashes in manually adjusted position.

Another object of the invention is to provide both sashes and sash guides so constructed and arranged as to permit ready adjustment, individually or together, so as to regulate interrelated friction, preclude free relative movement, end rattle and to be self-compensating with respect to wear and expansion due to temperature changes.

A further object is to provide a construction of the type outlined which avoids the necessity for glass securing means such as putty or the like and which will present a finished and attractive appearance without requiring paint or supplemental decorative means.

The novel features that are considered characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawings, wherein like reference characters indicate like parts throughout the several figures and in which:

Figure 1 is a front elevation of one form of my new and improved sash and sash guide construction;

Figure 2 is an enlarged fragmentary detail sectional view, taken on Iline 2 2 of Fig. 1;

Figure 3 is an enlarged fragmentary detail sectional view, taken through the upper frame of the window on line 3-3 of Fig. 1;

Figure 4 is an enlarged detail fragmentary plan view, taken on line 4-4 of Fig. 1;

Figure 5 is an enlarged fragmentary sectional View, taken on line 5-5 of Fig. 1;

Figure 6 is an enlarged fragmentary sectional plan view, taken on line 6-6 of Fig. l;

Figure 7 is a fragmentary front elevation of the sashes in adjusted relation; and,

Figure 8 is a fragmentary perspective exploded view of one of the side guideways and the upper horizontal weather strip or seal.

Referring to the drawings in that form of my invention here presented by way of example the usual window casing is indicated Vat C, consisting of vertical Stiles or side ICC rails 1, connected together at their upper ends by the yoke 2, and having the usual sill 3 at their lower ends. With the present invention, the usual stops and parting stops from the inner sides of the window stiles or frames are eliminated, my new and improved sash and sash guides consisting of metallic members generally indicated at 4, in Fig. l rendering ysuch devices unnecessary. As indicated more in detail in Figures 6 andl 8, the guide- Ways comprise elongated base portions 5; extending inwardly from such base portions toward the sash of the window are V-shaped guides or tongues 7 and 8. One of the legs 9 of these V-shaped guides extends at right angles to the base 5, while the opposite leg 10 extends Iat approximately 60 from the base 5, both legs coming together in the reverse bend 7A and 8A.

The window sashes are constructed in the following manner: The glass 11 is held within a metallic frame V12, which completely surrounds the glass. This frame cornprises a Ushaped channel 13 embracing the outer edge of the glass. The channel 13 has one of its legs 14 on one side of the glass and is Ibrought down to 4a reverse bend 15, extending up on the opposite side of the glass by its 4oppositely disposed leg 16. A reverse bend at 17 terminates the leg .16, provides at an angle of approxi mately 30 an outer edgerl. A V-shaped groove v19 is thus `provided extending completely around the Yglass which is enclosed thereby. The lower sash further includes a reverse bend 20 bringing the materia-l 21 to the point 22 where it is fxedly secured to the reverse bend 15.

As indicated the V-sh-aped vertical guides or tongues 7 and 8 are adapted to cooperate with the V-shaped grooves of the sash. Thus the upper sash and outer sash 23 is adapted to be guided by the guideway 7 working Within the V-shaped groove 19, while the inner and lower sash 24 is adapted to be guided by the vertical guideway 8 working within the groove 19 of the said sash. The bases 5 of the vertical guideways 7 and 8 are secured to the stile 1 of the window casing by the screws 25 operating Within the slots 26. In this manner the expansion or contraction of the V-shaped guides 7 and 8 is permitted without either loosening or tightening the guides within the grooves 19 of the sash and providing an adjustable sliding contact between the two, not only to maintain the necessary friction for holding the window at any desired point, but also to insure an air tight weather seal. By this construction not only is special weather stripping unnecessary but the necessity of counterweights on the window sashes is eliminated.

In order to align and seal the upper edge of the upper sash 23, a weather strip 27 is iixedly secured to the transverse yoke 2 of the window casing by way of screws 28, which hold the strip to the yoke by way of the slots 29. This Weather Strip 27 has a tongue 3? corresponding to the tongue 7 of the vertical guides. Slots 29 permit adjustment of the V-sh-aped tongue 31) within the horizontal grooves 19 of the upper sash. The upper V-shaped tongue 31) prevents the window sash from rattling and weather seals the same. The tongue 30 is adapted to align with the V-shaped guides 7 coming together on the line 37 (see Fig. 7). As best shown in Figure 5, a second weather strip is secured to the upper side of the sill 3.

Said strip has a base 34 provided with a slot 36 `and isV adjustably held in place on sill 3 by screws 35. Said strip is provided with a tongue 32 extending upwardly from its base to engage the V-shaped groove 19 formed on the lower side of the lower sash 24. The tongue 32 operates within the groove 19 permitting adjustment of the depth of the tongue within the groove 19 of the sash so that the same can be adjusted to the exact fit.

ln the operation of my new and improved window sash and guideways, the guideways can be adjusted by fit within the grooves surrounding the sash so that a.

proper friction can .be maintained for holding the sash at any desired elevation, as Well as providing a complete weather seal around the sash. Further, with my new and improved construction, all of the contacting parts, tongues and grooves are made of metal,` a metal requiring no paint or finish, therefore the friction is always the same regardless of Weather conditions, and at all times presenting 'a pleasing eiect to the eye, without requiring paint or the like.

Although a certain specic embodiment of the invention has been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.

What I claim is:

1. In combination, a window sash having angular grooves along its edges, and a guide comprising a flexible sheet member having inwardly extending angular portions for iitting in an angular sash groove and fiat substantially coplanar base portions extending laterally from the outer edges of said angular portions and provided with slots, and means engaging said slots for adjustably securing Said base portions to a frame within which the sash is to be mounted to provide adjustment of the base portions toward or away from each other and selectively vary the angle of the angular portions of the guide to regulate the interrelated friction between the guide and the angular groove of the window sash.

2. In combination, a window sash and sash guide, said sash comprising a glass receiving and retaining frame including a peripheral U-shaped glass receiving member and an outwardly open V-shaped channel, said sash guide comprising a flexible sheet metal member having inwardly extending angular portions and laterally extending fiat base portions provided with slots, means engaging said slots for adjustably securing said base portions to a frame within which the sash is to be mounted for adjusting of the base portions toward or away from each other to selectively vary the angle of the angular portions of the guide to regulate the interrelated friction between the guide and the V-shaped channel of the sash.
